Yeah, we also did put milk in it too. I think that is needed in most real milkshakes.
Sounds also very yummy how you have had it. I have never tasted it that way, but I am sure it is worth a try.
Well, the fruit we tried it out with was most banana bites. But still, I am very sure that strawberries bites must be very nice too... And probably a lot more as well. Just a matter of being creative!
